Facebook SDK restarts app

Whenever I use the Facebook SDK to login to Facebook it restarts the app.

I Post to facebook, launches the dialog prompting for login. I login. When it transitions back to my Unity App, it goes back to the splash screen just like the app was freshly opened.

Anybody else dealing with this bug? Any fixes?

UPDATE

Facebook crashed my app due to memory?

In ios xocode project change the info.plist
Change application does not run in background = NO
